| 摘要: 本文采用水热技术合成了一种多钒氧酸盐[NH3(CH2)4NH3][H2pip]2[V10O28]·6H2O (1，pip=哌嗪)，并且通过元素分析、红外、热重、单晶X-射线衍射对化合物1进行了表征。化合物1为单斜晶系,空间群为P21/n,晶胞参数为a=1.229 85(10) nm,b=1.075 10(9)nm，c=1.496 71(12) nm，β=93.947 0(10)°，V=1.974 3(3) nm3，Z=2。晶体结构分析表明，化合物1是由[V10O28]6-阴离子簇、质子化的1，4-丁二胺和哌嗪阳离子以及结晶水构成。有机阳离子和结晶水通过O-H…O和N-H…O氢键相互作用将阴离子连接形成三维结构。 | |

| Abstract: A polyoxovanadate [NH3(CH2)4NH3][H2pip]2[V10O28]·6H2O (1, pip=piperazine) has been synthesized by hydrothermal method and characterized by elemental analysis, IR, TGA and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/n, with cell parameters of a=1.229 85(10) nm, b=1.075 10(9) nm, c=1.496 71(12) nm, β=93.947 0(10)°, V=1.974 3(3) nm3, Z=2. Crystallographic analysis reveals that it is constructed from anionic cluster [V10O28]6-, protonated 1,4-butanediamine and piperazine cations, as well as waters of crystallization. Organic cations and waters of crystallization further connect the anions into a three-dimensional framework by water-anion hydrogen bonds O-H…O and cation-anion N-H…O interactions. CCDC: 848090. | |
